IMPROVEMENT IN PE|\1c||` v s.V

'Specification forming part ofLetters VPatent No. 43,391, dated 4July 5, 1864.

`To a/ZZ whom it may cor/wem.'

Be it known that l, OEEsrEs CLEVELAND, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Pencils; and I do hereby declare4 that the following is a full, clear,.and 4exact description of the same, ref- 'erencebeing had to the accompanying drawing, making a part-of this specification, and to the letters ot' reference marked thereon.

1n the ordinary method ot constructing wooden lead-pencils the lead is laid in a groove in the iat side of a prismthat vis somewhat ,larger than a semicircle in section, and the pencil is completed, so'far as the inclosureof the lead is concerned, by gluing a fiat pieceA over the lead 'to complete thecircle of the section and ferm an entire cylinder. In anothercommon method the groove for'th'e reception of the lead is plowed into the wood from.

the exteriorof the cylinder, and after placing the lead in the bottom of thegroove the remainder is tilled with a suitable slip of wood, o'f the same width as the lead, which is. glued into it. The objection to both these methods, and that which-my invention is intended to '0bviate, is that the 'supplementary pieces of wood'glued to 4the pencil for'the purpose of retaining the lead-in position are likely to become loose and split ott', especially-when the pencil is exposed to damphess or any other cause that would affect the tenacity of the glue.

- My invention consists in dovctailing the supplementary piece of wood into the body of the pencil in such a manner that it is not, likely'to get loose, and that it can only'be raken-outof-the grooveby removing item1` wise.

To enable others skilled in the arts to which it appertainsto make and use my invention,

usual manner.

I will proceed to describe its construction and operation with reference to the drawing, which represents a pencil made according to the mannerl have described. l

The lead tt is inclosed in a cylinder of eedar,r

b, or'other suitable material, in which has beenA plowed a groove with a rectangular bottom of the requisite'l size for its reception. The outer part of the groove is cut 'in the form of a dovetail, in the manner shown, with the nar row part sufficiently wide for the' passage of Ithe. lead, and this dovetailed portion is closed and filled by the piece c, which is inserted from the end and closely fitted and glued in the cil may beconstructed as shown in the supplementary figure marked The pencils may be made cylindrical vor hexagonal and finished in any desirable manner without departing from the principle of my invention, which consists in closing the groove for the reception ot' the lead with a supplementary dovetailed piece whichfdoes not depend simply-upon the adhesiveness of the glue 'toret'aiu the parts together; and although I have described the application o't' my invention to black-lead pencils only, it is 'obvious'that the sameprinciple of construction may be employed in all those varieties of pencils in which coloredV crayons, French chalk, slate-pencils, india-rubber, and other matter may be used asa core inclosed in a prism of wood or other suitable material.

I claim, as a new article of manufacture- A pencil constructed with the parts glued together with dovetailed joints, substantially as described.
